Hi,

According to Google Play Billing release page:
Starting on August 2, 2022, all new apps must use Billing Library version 4 or newer. By November 1, 2022, all updates to existing apps must use Billing Library version 4 or newer.

We are using Unity 2018.4.36f1 which is a LTS version of Unity. There is a problem migrating to IAP version 4.4 which used Google Play Billing version 4 since the newest IAP supported by Unity 2018 is 2.2.2.

We’ve tried importing newer IAP into the project but the new unity.services.core which is a dependency to com.unity.purchasing@4.4.1 can not be imported. we also tried to find com.google.play.billing newer versions but the latest version available for unity is 3.5.2 which is does not solve the problem.

Since the game is bein developed on an LTS version of Unity, we expect support for this issue, what is your suggestions?

Unity 2018 LTS is out of support since 2 years ago (early 2021). You do not expect Unity to support all versions forever just because it is called LTS? :slight_smile: Each LTS version has officially 2 years of support.

Unity IAP 4.4+ requires Unity 2020.3 or later.
